HOT-WATER TUBE Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed October 28, 1907. Serial No. 3959,4596.

T all whom it may concern:

Be it known that I, LEO H. Mnnns, a citizen of the United States, residing at Lorain, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Hot-Water Tubes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hot water tubes, and has for its object to provide a tube with a longitudinally arranged partition, by means of which the water will be caused to pass lengthwise of the tube twice.

Another object is to provide means by which the partition may be removed if desired, and also to permit of the tube being cleaned with or without removing the partition.

Another object is to provide means for connecting a set or series of said tubes at one end, without the use of a return bend, whereby the water may be caused to circulate through all of them, and, finally, communicate with a manifold at the upper end.

In the accompanying drawings, which illustrate the invention, Figure 1 is a broken perspective view of one form of heater provided with my improved tube; Fig. 2 is an enlarged perspective view of a section of tubes, showing one means of connecting them to gether; Fig. 3 is a longitudinal sectional view of one of the tubes, and Fig. 4 is a cross sectional view of the same.

Referring more particularly to the drawings, 1 indicates a tube which may be of any desired length and size and also of any desired shape in cross section, although I prefer to use the ordinary cylindrical tube.

Each end of the tube may be closed in any manner, as by a ca 3, as shown, or by plugging the same, or y casting one end of the tube solid. The front end of the tubes are preferably provided with a suitable T, as 4, and joining Ts of the same vertical series by means of nipples, 5. But it is evident that other forms of connecting the pipes together could be used, as a screw joint, ground joint, or ordinary flanges, none of which are shown, as they are of the ordinary construction and form no part of the present invention.

When the ordinary push nipple is used, keys or connectors at the ends of the tubes are preferably held together by means of draw rods, 6, which extend through suitable ears, 7, or perforated projections upon said connectors. Partitions 7 extend horizontally from the front end of the tubes 1 to near the rear end thereof and are supported by inwardly projecting flanges 7 this is the pre ferred form of partition, but in any and all forms of tube connectors or partitions, the forward ends of the partitions are intended to extend out to the forward end of the connectors, so as to make an impervious wall between the upper and lower portions of the tube and its connector, and to provide a passage at the rear or innermost end of the tube through which the water can pass from the lower to the upper portion of the tube as it becomes heated, and is caused to circulate from the bottom to the top of the entire se ries. In this manner the water is exposed for a longer time to the action of the heat while passing through each tube, thereby virtually doubling the capacity and efiiciency of the furnace. After passing through the tubes in this manner, the water from the upper tubes communicates with a manifold, 7, in any desired manner, as by the tubes 8, and from there it passes to the point of use or consumption in any desired manner. Where the water is used for heating purposes, as by circulating it through radiators, etc., it returns to the lower tubes and from there it passes up through the tubes within the heater into the manifold and again through said radiators. It is evident that steam could be caused to circulate through the tubes and the system of heating in the same manner as the water, and could be subjected to the action of the fire in the furnace in the same manner.

I prefer to inclose the tubes in a furnace or heating receptacle, as 9, which can be provided with suitable means of heating it, as

coal, gas, etc., an ordinary gas heater being shown in Fig. 1. I also prefer to surround the heater with any suitable form of acket or casing 10, from which hot air pipes can lead to any desired point in the ordinary manner. By circulating air among the tubes and causing hot water or steam to circulate through the tubes, the entire device can be used as a hot air furnace, and the air can be distributed through the hot air pipes as desired. The tubes can be supported on a shelf inside of the front or rear wall, or they can be reversed to make them run oppositely through the sides, if desired.

As above described, it will be seen that my o or shoulders, and either end of the tube may be provided with means for gaining access to its interior, and thereby removing the sediment or the partitions, or both.

Having described my invention, I claim:

5 1. In a hot Water heater, a furnace, a plurality of hot water tubes therein, each of which is provided at its forward end with a connector, said connectors being provided with laterally extending perforated cars,

o draw rods through said ears for uniting said tubes into a series, and a partition extending longitudinally through each tube, the forward end of which forms an imperforate wall in the connector and the rear end of :33 which terminates near the rear end of'said tube whereby is formed a passage from the lower to the upper portion of the tube.

2. In a furnace, a tube having inwardly projecting ribs, a partition removably resting on said ribs and a removable cap for one end of said tube, said cap being provided with openings above and below said partition.

3. In a furnace, a tube closed at one end and having inwardly projecting longitudinal ribs, a removable partition resting on said ribs and extending nearly to said closed end, aT having an upper and a lower opening and removably fitted into the end of said tube, one end of said partition extending into .said T between said openings, and fluid connections to said openings.

4. In a furnace, a series of tubes, a T fastened to an end of each of said tubes, nipples connecting the arms of said Ts, perforated projections on the ends of the arms of said Ts, and a draw-rod extending through said perforated projections.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

LEO H. MERES.
